Patented Nov. 24, 1953 PARTITIONED CARTON Walter J. Tyrseck, Montville, Conn., assignor to Robertson Paper Box Company Incorporated, Montville, Conn., a corporation of Connecticut Application August 8, 1950, Serial No. 178,187

3 Claims. (01. 229-28) This invention relates to cartons. It is an object of the invention to provide an improved compartmented carton.

A further object of the invention is to provide a folding carton in which a single blank may be used to form an outer box, center partition and cross partitions, the collapsed box being capable of setting up by merely applying pressure to its edges.

With these objects, as well as others which will appear, in mind, a carton embodying the invention in a preferred form will now be fully described with reference to the accompanying drawing and then be more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a flat view of a blank used for making the carton;

Figures 2, 3 and 4 show the progressive foldings and gluings involved in producing the collapsed carton;

Figure 5 is a back view of the collapsed carton of Figure 4;

Figure 6 is a plan view showing the carton expanded or opened up and with the bottom flaps closed in readiness for insertion of the contents; Figure '7 is a section on the line 1-1 of Figure 6; and

Figure 8 is a section on the line 8-8 of Figure 6.

The box selected for illustration has twelve 5 compartments, formed by a longitudinal partition and five cross partitions to either side thereof.

The box walls are formed from an aligned series of panels I, 3, 5, l and 9 arranged for folding on the score lines 2, 4, B and 8.

Bottom panels or flaps i I, l3, l5 and I! are provided to form a bottom closure and are hingedly connected to the wall panels along score lines l2, l4, I6 and I8. Bottom panel ii is formed with cut outs l9 and 20, as shown, and panel carries a locking element 2 I, hinged to it on score lines 22 and having projections 23 and 24 for cooperating with the cuts [9 and. 23 in the known manner.

Top panels or flaps 25, 2'! and 29 are hinged to the wall panels on score lines 26, 28 and 30, and panel 29 has a tuck-in extension or flap 3| hingedly connected to it on score line 32.

Panels 33 and 35, hingedly connected to panels I and 5 along score lines 34 and 36, are the elements forming the partitions. In the carton shown, the compartments are to be of equal size, and the outer edge 38 of the panel 35 terminates short of fold line 2 at one end of wall panel I by a distance equalling half the width of adjacent panel 3. The other end of edge 38 extends beyond the corresponding other end of wall panel I, by a like distance. The panel 33 has thus the general outline of a slant parallelogram rather than the usual rectangle.

Similarly, outer edge ll) of panel 35 extends beyond fold line 4 by half the width of panel 3 and falls short of fold line 5 by a like amount. Panels l and 5 are shown as longer than panels 3 and l, in the ratio of about two-to one. Rectangular boxes of other shapes may be formed by changing this ratio, but in any event, panels I, and 5 will be of equal width, and panels 3 and. 7 will be of equal width, where a rectangular box; is desired.

Panels 33 and 35 are shaped and cut out as: shown, having a series of diagonal cuts 42, trans-- verse cuts 45 and longitudinal cuts 45. The ends;

of transverse cuts 54 are connected to the di--' agonal cuts 42 by longitudinal score lines 48 and. the longitudinal cuts 45 are continued by longitudinal score lines 53 which also meet the di-- agonal cuts 42. These various cuts and fold lines: divide each of the panels 33 and 35 into the fol-- lowing elements: an inner marginal portion (43 in Figure 8) running along fold line 34 or 36, as the case may be, and which will lie flat against the corresponding wall I or 5 in the completed box; an outer marginal portion (45 in Figure 8) which is to form the longitudinal partition; and a number of diagonal strips (41 in Figure 8) which form the cross partitions.

In forming the carton from the blank of Figure 1, the areas a and bare first spot glued and panels 33 and 35 are folded over onto panels I and 5 and joined thereto, as shown in Figure 2.

Next, one or both of the panels 33 and 35 is spot glued over an area 0 and the blank is folded over on line 2, adhesively joining the marginal elements of panels 33 and 35 together, and producing the structure of Figure 3.

Finally, area at of panel I is spot glued and the blank is folded over on line 5, adhesively joining panels I and 9 and producing the collapsed carton of Figure 4.

The collapsed carton of Figure 4 is opened up by pressing its ends toward each other and the bottom flaps are folded to close the bottom putting the carton in the condition of Figure 6, ready for loading.

The completed box thus comprises a number of panels forming the walls and a central partition formed of the outer edge strips 38 and 40 and partition forming panels together with the diagonally extending strips 41 connecting the cencondition does not more tits 3 ter partition to the opposite side walls to form cross partitions. In Figure 1 the angle of the cuts 42 to the hinge line 34 (which angle is the same in the other partition forming panel 35) is indicated at A, and the length of the diagonal strip from vertical fold line 48 to vertical fold line 50 is indicated at D. By reason of the fact that the partition forming panels are first folded over on the wall panels to which they are attached, and that they swing in an arc in opening out from collapsed condition to the condition of Figure 6, the angle of slant of strips 41 as shown in- Figure 8 will be the same angle A as indicated in igure l. Thus (apart from the usual al'l6tt' ':e for th ness of materials and folds) j it will s the length of the strip 41 (D cosine of the angle A will be equal to one half the width of panel 3 or panel 1. It will secondly be observed that the movement of the center'par: tition in opening out the carton from collapsed een ter' ear-mam vertically so that proper deem in fife hex by sl'iitably' I widthof the partition refining an and '35 as measured at right angle to wage v es 3 and 3E While a carten or twelve ompartme" is show-F1 it will be apparent that the Sa ine principlesor construction beap'p'liedto form eartonsnaving various numbers or compartments.

4 a a pair of partition forming panels hinged to the edges of two alternate wall panels, each such partition forming panel being generally of the forrn of a slant parallelogram, having a strip adjacent its hinge edge foldable flat against the wall panel to which it is attached, a strip adjacent its opposite edge positioned for attachment to the corresponding strip of the other arents. formin panel when the partition panels are folded over on the wall panels and the wall panels are folded over on their score lines, and a plurality of di- Agassi slits forming diagonally extending strips conne ting said edge strips.
